Now, let's get to the fun part – grilling! You'll want to preheat your grill to medium-high heat, around 400°F to 450°F. While you're waiting for the grill to heat up, take a moment to think about the perfect doneness you're aiming for – do you like your asparagus slightly crunchy or more tender?
As you throw your asparagus spears onto the grill, you might be wondering, how long do I actually cook them? The answer is, it depends on the thickness of the spears and your desired level of doneness. As a general rule of thumb, you can expect to cook thin spears for around 3 to 5 minutes per side, while thicker spears might need 5 to 7 minutes per side.
Here's a cool comparison to help you gauge the cooking time: think of grilling asparagus like cooking a steak – you want to get those nice grill marks and a bit of charring on the outside, while keeping the inside tender and juicy. Just like a steak, asparagus will continue to cook a bit after you remove it from the grill, so keep that in mind when checking for doneness.
